Genes affected

WFIKKN2 (HGNC:30916): (WAP, follistatin/kazal, immunoglobulin, kunitz and netrin domain containing 2) The WFIKKN1 protein contains a WAP domain, follistatin domain, immunoglobulin domain, two tandem Kunitz domains, and an NTR domain. This gene encodes a WFIKKN1-related protein which has the same domain organization as the WFIKKN1 protein. The WAP-type, follistatin type, Kunitz-type, and NTR-type protease inhibitory domains may control the action of multiple types of proteases. [provided by RefSeq, Jul 2008]

The c.619A>G (p.M207V) alteration is located in exon 2 (coding exon 2) of the WFIKKN2 gene. This alteration results from a A to G substitution at nucleotide position 619, causing the methionine (M) at amino acid position 207 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
